Best ResponseYou've already chosen the best response.1c^2 9 can be factored to (c+3)(c3) (3c) a neg sign can be factored out > (c3) common denominator is (c+3)(c3) combined fraction should look like this: \[\frac{(c3) + (c ^{2}3) (c+3)}{(c+3)(c3)}\] add like terms on top \[\frac{c ^{2}9}{(c+3)(c3)}\] FOIL the bottom and then it cancels leaving 1.
